Silicon Labs Intros Single-die, All-in-one Digital Radio IC

Austin, TX - Apr 22 2013 - Silicon Labs has unveiled its new monolithic Si468x receiver IC, what it says is the first single-die antenna-input-to-audio-output digital radio receiver chip. Using software-defined radio technology, the receiver IC brings FM, HD Radio and DAB/DAB+ broadcast capabilities to a wide range of consumer devices.

The Si468x receivers support auto-calibrated digital tuning and FM seek functionality based on multiple signal quality and band parameters and provides flexible audio processing features including noise blanking, configurable FM soft mute, FM de-emphasis and FM hi-cut filtering. Additionally, the Si468x receivers have an integrated decoder for the European Radio Data System (RDS) and North American Radio Broadcast Data System (RBDS) standards including required symbol decoding, block synchronization, error detection and error correction functions.

The Si468x family includes the first monolithic digital radio receiver ICs certified by iBiquity to support the HD Radio standard for portable and consumer electronics applications. The Si468x receiver family is compatible with the European Eureka 147 DAB and DAB+ standards and is designed to be fully compliant with the United Kingdom's Minimum Specifications for DAB and DAB+ personal and domestic digital radio receivers.

The family's wafer-level chip-scale package (WLCSP) option supports very compact designs, enabling a complete digital radio receiver system with only 12 external components to be implemented in less than 100 square millimeters.
